First of all, I'm sorry to learn the author got cancer; I wish her all the best and continued strength. Many contributors have already made good suggestions how to reduce the risk of getting cancer, or how to deal with it; but I found most posts quite _technical_.

Sure, eventually. It's one thing if people are getting cancer or having heart attacks later in life. It's a little concerning when a fairly large number of younger people are afflicted. The rate of cancer has risen about 30% for young people since the seventies. So it seems that there's something wrong in our environment or lifestyles that could be increasing risk. That's very concerning in my opinion.

And on the subject of dying from a heart attack in one's 20s. That's "significant", but 1 in 100,000 is pretty rare. Some could be congenital or obesity related, but the majority in that age group is due to substance abuse. That's a factor people can control, and thus not as scary to most people.
